2. Description of the Related Art Generally, an elevator hoistway is provided in a place where it will not be submerged in the rain, and the bottom of the hoistway is waterproofed so that a car and a counterweight will not be submerged. However, due to unexpected heavy rain and typhoons, drainage channels and rivers may flood, flooding the road with rainwater, and causing rainwater to flow into the building. Then, if the water level is further increased, water may be infiltrated through the gap between the door of the elevator hall and the groove of the sill, and the elevator car may be flooded, causing damage to the equipment and deterioration of insulation, which may lead to a serious accident. Further, when the elevator hall faces the outdoors, there is a possibility that rainwater may directly enter due to strong wind.

Therefore, when a heavy rainfall occurs, the maintenance personnel who maintain the elevator go to a building that is likely to be flooded, evacuate the car to a safe floor, and then turn on a pause switch to prevent the elevator from operating, It is designed to prevent damage to the equipment.

Further, as described in Japanese Utility Model Laid-Open No. 154265/1983, a flood sensor is provided for detecting flooding when the elevator is moved up and down, and when the flood sensor detects the flooding, the elevator car travels to the flooded point. There has been proposed an elevator emergency operation device that does not.

[0005]

By the way, as described above, it takes a lot of labor and time for maintenance personnel to go to a building that is likely to be flooded. Therefore, go to all buildings that may be flooded and take evacuation measures. In order to do so, the work has to be started quite early, which leads to a long elevator downtime, which is inconvenient for the elevator users. Furthermore, it is difficult to deal with sudden heavy rain.

Further, providing the flood sensor for detecting flood in the hoistway of each building like the latter is problematic in terms of cost, and the flood sensor is actually installed in only a limited number of buildings. is the current situation.

The present invention has been made in view of the circumstances in the prior art as described above, and an object thereof is to prevent maintenance personnel from going to a building likely to be submerged and providing a submergence sensor in each building. Another object of the present invention is to provide an elevator submersion prevention device that can effectively prevent submersion by shortening the elevator stop time.

[0008]

In order to achieve this object, the present invention provides a plurality of buildings, each of which is equipped with an elevator, in a predetermined area, and remotely monitors these buildings via a telephone line. And a monitoring center for preventing the flooding of the elevator car and the counterweight due to the flooding of the building, the flooding prevention device for the elevator, wherein the monitoring center includes at least one of the plurality of buildings. When it is confirmed that there is a possibility of flooding in one building, command output means for outputting the evacuation command and the evacuation operation start time is provided, and the evacuation command and the evacuation operation start time are provided for each of the plurality of buildings. And a storage unit that stores the data and operates to a position where the elevator car and counterweight do not flood at the evacuation operation time. Both are a configuration that includes a signal output means for outputting the evacuation signal for prohibiting operation to the position where the flood has passenger cage and the counterweight.

[0009]

Since the present invention is configured as described above, when it is confirmed that at least one of the plurality of buildings is likely to be flooded, the evacuation command and the evacuation command are issued from the command output means of the monitoring center. The operation start time is output to all the buildings including the building via the telephone line. The storage unit of the building stores the evacuation command and the evacuation operation start time, and at the evacuation operation time, an evacuation signal is output from the signal output means, and the elevator car and the counterweight are operated to a position where they do not flood, and Cars and counterweights are prohibited from operating where they are flooded. This will prevent the maintenance staff from going to a building that is likely to be flooded and prevent flooding without having to install a flooding sensor in each building, and shorten the elevator downtime because the evacuation operation time is set. And effectively prevent flooding.
